Anthony Valento, a 17-year veteran of the Burbank Police Department, is accused of lying to federal officials during an extortion investigation involving the officer, his girlfriend and her estranged husband.

“There’s no evidence that other people were involved or had knowledge of what was occurring,” LaChasse said of the allegations against Valento.

Burbank internal affairs investigators — initially without knowing about the federal corruption investigation into Valento — have been investigating the officer since around May for alleged misconduct because that month, a superior noticed Valento’s response times to calls for service were delayed, records show.
